Title: Emmanuel W Oomen: Innovator in Electrochromic Technology
Introduction
Emmanuel W Oomen is a notable inventor based in Eindhoven, Netherlands. He has made significant contributions to the field of electrochromic technology, holding a total of 6 patents. His work focuses on developing innovative solutions that enhance the functionality of display devices.
Latest Patents
One of his latest patents is an electrochromic element that comprises an electrochromic layer whose transmission properties change when a voltage difference is applied across the element. This electrochromic layer includes a first metal oxide from a group consisting of WO.sub.3, MoO.sub.3, Nb.sub.2 O.sub.5, MnO.sub.2, and ZrO.sub.2, along with a second metal oxide containing V.sub.2 O.sub.5, TiO.sub.2, and/or ZnO. The concentration of the second metal in the mixture ranges from 1 to 15 at. %, preferably from 3 to 10 at. %. When no guest atoms are incorporated, the electrochromic layer remains transparent and colorless. However, with a substantial concentration of guest atoms, it appears grey. These electrochromic elements are particularly useful on the outer surface of display screens in display devices.
Another significant patent involves a display device that features a display screen coated with a spectrally selective, light-absorbing coating made of silicon oxide and at least two dyes. The spectral transmissions for blue, green, and red phosphor light are designed to ensure that the electron currents towards the phosphors for achieving white D (6,500K) are substantially equal.
